Abstract :
A novel design method of one-sided directional printed slot antenna for high-band ultra wide band (UWB) systems is proposed. For realize the one-sided directional radiation, we applied the floating metal layer on the bottom of the antenna substrate. By optimizing the lengths and widths of the antenna slot and substrate, three resonances can be obtained at different frequencies. By independently controlling three different resonances on the slot and antenna substrate, we can realize the wide band impedance matching. The final antenna size is 29 mm × 16 mm × 1.6mm. Our proposed antenna was fabricated on the FR4 substrate and measured impedance bandwidth is 2.58 GHz from 7.74 to 10.32 GHz. Moreover one-sided directional radiation can be obtained.
